LOCK.

Specification of I-.etters Patent.

Patented Oct. 26, 1909.

'Application filed January 5, 1909. Serial No. 470,811.

To all whom it may concern:

Be it known that I, JOHN F. BEATTY, a citizen of the United States, residing at Morton, in the county of Delaware and State of'Pennsylvania, have invented certainnew and useful Improvements in Locks, of which the following' is a specification.

lily invent-ion relates to improvements in locks, more particularly designed for inside use, as for instance upon a cupboard, wardrobe, and similar doors, and which can be readily operated by any one familiar with a lock, but which will be difficult for anyone not familiar with a lock to operate.

A further object is to provide improved locking means, which render it impossible to operate the lock until the proper key is inserted.

With these and other objects in view, the invention consists in certain novel features of construction, and combinations, and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a View in longitudinal section illustrating my improvements in locking position. Fig. 2, is a similar view showing the parts in unlocked position. Fig. 3, is a view in section at right angles to Figs. 1 and 2. Figs. 1 and 5, are views of details of construction. Fig. G, is a view in section illustrating one of the operative positions'of the Darts. Fie. 7 is a detail ers ective view of the plunger, and Fig. 8, is a detail perspective view of the tumbler.

1 represents a lock casing in which parallel bolts 2 are mounted to slide, and are connected by a cross bar 3. This cross bar 3 is secured to the bolts 2 by means of screws ll, and is preferably curved downward as shown in Fig. 3, and notched and beveled at its center as shown at 5, for a purpose which will more fully hereinafter appear. The inner ends of the bolts 2 move in housings 6, and coiled springs 7, located in said housings, bear youtwardly against the bolts and normally force them into locking position.

A knob 8 is provided with a restricted neck portion 9, mounted to turn in an opening in the casing wall, and is provided with an eccentric disk 10 on its inner end, and a coiled spring 11 is disposed between the casing and the knob 8 to normally press the latter outward and hold the disk 10 against the inner face of the lock casing. This knob isV bored throughout, and a cylindrical plunger 12 is mounted to slide in the bore of said knob, and the said plunger is provided with an enlarged head 13 on its outer end, movable in an enlarged recess or socket 14 in the knob, as clearly shown.

A coiled spring 15, is disposed between the wall of the casing, and the inner end of plunger 12, and preferably projects into a socket in the latter to normally press the plunger outward as shown in Fig. 1. `This plunger 12 is provided at its inner end with a web 16 having a cam face to engage in the bevel or cam faced notch 5 of the cross bar 3, so that when the plunger 12 is forced inwardly, the cam action of the web 16 against the cross bar 3 will. draw the bolts 2 inwardly to unlocked position, and when the plunger is permitted to spring outward, the springs 7 will project the bolts to locking position.

The knob 8 and the plunger 12 are provided with lateral openings or recesses 17 and 18 respectively, which, when the plunger is in its extreme outward position, and the bolts 2 in locked position, are adapted to register, and sectional pin tumblers 19 located in said recesses, are so registered and held by means of coiled springs 20, the latter in the recesses 17 of the knob. These pin tumblers 19 are adapted to be engaged by a key 21 inserted in a key-way 22 in the plunger, and this key is so constructed and shaped, that when it is inserted, it will hold the sectional pin tumblers, so that the meeting edges of their sections, will exactly register with the meeting edges of the plunger and the knob, and permit the plunger and knob free independent movement. IVhen, however, the key is withdrawn, the springs 20 will project the pin sections across the meeting edges of the plunger and knob, and securely lock them against independent movement, and as the inward movement of the disk 10 on the knob 8 is limited, as will more fully hereinafter appear, it will be seen that the `bolts 2 will be securely locked.

A tumbler 23 is mounted in the casing, and provided withl pintles 24 at its ends, pivotally supporting the tumbler, and a web 25 on the tumbler is connected by a spring 2G with the casing 1, so as to h old said webbing against a pin stop 27 in the casing, and properly position a latch dog 28, which latter is adapted to enter a notch 29 in the disk 10, and when in said notch, the locking pin sections will be registered so as to enable the p device to be locked. y

When the key is in the lock and the knob is turned, it will be observed thatthe removal of the key cannot lock the parts, and hencefor the ordinary. use, the parts would be so positioned Then it is desired to securely lock the parts, the knob 8 is moved inward to the position shown in Fig. 6,'thisV described without departing from my inven-V tion, and hence I do not restrict myself to the precise details set forth, but consider myselil at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. Inra lock, the combination with a sliding bolt, ofy a plunger, said plunger and said bolt so constructed that the inward movement of the plunger will draw back Vthe bolt, av knob having rotary mounting on said plunger, and pin tumblers in said knob and plunger securely locking them together.

2. In a-lock, the combination with parallel locking bolts, a cross bar connecting the bolts, an outwardly spring-pressed plunger, and a web on said plunger havinga cam face in engagement with a cam face on said cross bar, a rotary knob on said plunger, and pin tumblers locking said knob andplunger to-Y gether.

3. In a lock, the combination with locking bolts, springs normally pressing said bolts outwardly, a cross bar connect-ing said bolts, and having a cam face, a plunger, a cam shaped web on said plunger' engaging the cam face of the cross bar, a rotaryfand longitudinally movable knob on said plunger, and means for locking said knob and plunger. against independent movement.

t. In a lock, the combination with locking bolts, of a longitudinally movable plun- IVhen in this position, theA having rotary mounting on said plunger, saidl knob and plunger having registering openings, sectional pin tumblers inY said openings, and a key in said plunger' constructed to Vhold said sectional pin tumblers, so as to permit independent movement of the plunger and the knob. V A

5. In a lock, the combination with a longitudinally movable bolt-moving plunger, of

a knob having rotary mounting on said plunger, a pivoted spring held tumbler, a

dog on said tumbler, a disk on said knob having a notch to receive said dog, said knob and plunger having openings normally in register when the said dog is in the notch of the disk, sectional pinY tumblers` insaid openings or recesses, and a key in said plunger constructed to position the sectional pin tumblers, so as tov permit independent movement of the plunger andthe knob.

G. In a lock, the combination with a lock casing, of a knob, a restricted neck portion on thevknob having rotary mounting in the lock casing, a disk on the neck portion and located within the lock casing, a spring beg tween said knob and the lock casing, a tumbler within the lock casing, a web on said tumbler, a spring pressing said web in one direction, a stop in the casing limiting the movement of the said web in that direction,

a dog on said tumbler adaptedl to enter a hold said pin tumblers, so as to permit inde-v pendent movement of the knob and the plunger. Y s

7. In a lock, the combination with a ,sliding bolt, of a plunger constructed to move said bolt,'a knob having rotary and longipin tumblers, so as to permit independent knob and said plunger having openings adapted to register, pin tumblers in said openings, and. meansfor indicating when the openings in saidknob and plunger are in register.

8. In a lock, the combination with-a sliding bolt, of a plunger constructed to move said bolt, a knob hav-ing rotary and. longitudinal mounting on said plunger., said knob and said plunger having openings adapted to register, pin tumblers in; said openings, a notched disk on saidV knob, and a dog adapted to enter said notch when the openings in said knob and plungerv are in ger'constructed to unlock said bolts, a knob A normally registering openings, pin tumblers in said openings, a notched disk connected l naine to this specication in the presence of With said knob and located Within the cas two subscribing Witnesses.
